virtual void DataTransferKit::EntityShapeFunction::entitySupportIds	(	const Entity &	entity,
		Teuchos::Array< SupportId > &	support_ids
	)		const

pure virtual

Given an entity, get the ids of its support locations.

Parameters

entity	Get the support ids for this entity.
support_ids	Return the ids of the support locations for the given entity in this array.

Implemented in DataTransferKit::STKMeshNodalShapeFunction, and DataTransferKit::EntityCenteredShapeFunction.

virtual void DataTransferKit::EntityShapeFunction::evaluateValue	(	const Entity &	entity,
		const Teuchos::ArrayView< const double > &	reference_point,
		Teuchos::Array< double > &	values
	)		const

pure virtual

Given an entity and a reference point, evaluate shape functions of the entity at that point.

Parameters

entity	Evaluate shape functions of this entity.
reference_point	Evaluate shape functions at this point given in reference coordinates.
values	Entity shape functions evaluated at the reference point. Return these ordered with respect to those returned by entitySupportIds() such that values[N] gives the value of a shape function of the Nth support location of entity.

Implemented in DataTransferKit::STKMeshNodalShapeFunction, and DataTransferKit::EntityCenteredShapeFunction.

void DataTransferKit::EntityShapeFunction::evaluateGradient	(	const Entity &	entity,
		const Teuchos::ArrayView< const double > &	reference_point,
		Teuchos::Array< Teuchos::Array< double >> &	gradients
	)		const

virtual

Given an entity and a reference point, evaluate the gradient of the shape function of the entity at that point. A default implementation is provided using a finite difference scheme.

Parameters

entity	Evaluate the shape function of this entity.
reference_point	Evaluate the shape function at this point given in reference coordinates.
gradients	Entity shape function gradients evaluated at the reference point. Return these ordered with respect to those return by entitySupportIds() such that gradients[N][D] gives the gradient value of the Nth support location in the Dth spatial dimension.

Reimplemented in DataTransferKit::STKMeshNodalShapeFunction, and DataTransferKit::EntityCenteredShapeFunction.
